Question

20./ Determine v lt), t50. 5mH Toor + valt) - Je 1 252F

Answer 1

This question is related to the analysis of a series RLC circuit. First use S-domain to analyse the circuit find the requisite voltage around the resistor and then using inverse laplace transform convert it into time domain.

This queption to is related to a series RLC circuits m er gov Convert it into s-domain R & I M after replacing the source with goult) as it gets connected at t=0. gout)
